Migres

This package provides simple migration capabilities for any backend.

System requirements

• Go v1.21

Basic usage

The key type in this package is Module which allows mapping version strings to Migration interfaces. For example:

import "github.com/annybs/migres"

type MyBackend struct{}

func (mb *MyBackend) Module() migres.Module {
  return migres.Module{
    "1.0.0": migres.Func(mb.upgradeV1, mb.downgradeV1),
    "2.0.0": migres.Func(mb.upgradeV2, mb.downgradeV2),
  }
}

Call Module.Upgrade(from, to) or Module.Downgrade(from, to) in order to execute migrations. The module ensures migrations are all run in the correct order.
